Abstract

The invention relates to a central locking type direct running AC contactor, which belongs to the technical field of low-voltage electrical appliances. It includes moving and static contacts corresponding to each other. The moving contacts are installed on the movable bracket, the static contacts are fixed on the static contact fixing frame, the static contact fixing frame is fixed on the contactor base, and the bottom of the movable bracket is installed with The moving iron core of the pull-in electromagnet, and the corresponding static iron core below it is installed on the contactor base. It is characterized in that the pull-in electromagnet is installed at the center of the bottom of the movable bracket. The upper end of the iron traction iron core is fixed at the center of the bottom of the movable support, and the lower end is provided with a locking and tripping mechanism. Light weight, no power consumption, no noise during operation, and high reliability.

Description

technical field [0001] The invention relates to a central locking type direct running AC contactor, which belongs to the technical field of low-voltage electrical appliances. Background technique [0002] The AC contactor is the most widely used electrical device in electrical equipment. The direct-running AC contactor includes dynamic and static contacts corresponding to each other. The moving contacts are installed on the movable bracket, and the static contacts are fixed on the static contact holder. , the static contact fixing frame is fixed on the base of the contactor, the bottom of the movable bracket is installed with the moving iron core of the suction electromagnet, and the corresponding static iron core below is installed on the base of the contactor. When working, power is supplied to the coil of the pull-in electromagnet, so that suction is generated between the moving and static iron cores of the electromagnet, and the moving iron core pulls the movable support...
